FCW 625
Special flux cored nickel base wire for gas shielded arc welding
Description & applications
· Special flux cored nickel base wire for gas shielded arc welding
· Latest generation basic slag quality guarantees optimum metallurgical quality and attractive welder appeal
· Meets the NiCrMo-3 requirements
· Together with enhanced productivity, FCW 625 offers many other advantages compared to solid wires : improved weldability, almost no spatter, better arc stability, enhanced wetting properties, better bead aspect and shape, and use of classical M21 gas mixtures
APPLICATIONS
FCW 625 is suitable for welding and cladding nickel-based alloys such as alloy 625 or similar materials. It is also used for dissimilar welding of nickel based alloys to each other, to alloyed steels or to stainless steels and for joining 6% molybdenum super austenitic steels or 9 % nickel steel.
